The expression and possible role of integrin-focal adhesion kinase signal pathway in invasive pituitary adenomas were explored. Forty-nine human pituitary adenomas were detected for the expression of integrinbeta1 (INTbeta1) and focal adhesion kinase (FAK) by immunohistochemistry, and their correlation with the invasiveness of pituitary adenomas as well as between themselves was analyzed. The results showed that INTbeta1 was expressed in 46 cases (93.9%) and FAK in 36 cases (73.5%), respectively, and their expression levels were highly correlated with tumor invasiveness, but not with the tumor types. It was suggested that the integrin-focal adhesion kinase signal pathway plays a role in the invasiveness of pituitary adenomas.

Colorectal cancer is currently the third most common cancer worldwide,and there are still half of the patients undergoing recurrence and metastasis after surgical treatment,so it is necessary for colorectal cancer patients to receive radiation therapy routinely.Due to the side effects brought by radiotherapy,it is of great importance to solve how to minimize the radiation dose in radiation therapy and improve radiation sensitivity.In recent years,people discovered that microRNAs can not only be involved in the origins of colorectal cancer and progress,but also play a increasingly important role in cancer radiosensitivity.MicroRNAs can regulate tumor radiosensitivity by influencing tumor microenvironment and function on target genes.DNA damage response caused by radiation includes the activation of ATM,histone modification and chromatin remodeling,cell cycle arrest,damage repair and apoptosis.microRNAs can regulate tumor radiosensitivity through above processes.This review focuses on the mechanism of microRNAs in affecting DNA damage repair and prospects the future of microRNAs in influencing the sensitivity of cancer radiotherapy in clinical application.

Objective To investigate the life satisfaction and its related factors in primary caregivers of breast cancer patients. Methods The Life Satisfactory Index A (LSIA) and self-administrated questionnaire were used. The life satisfaction between breast cancer patients'primary caregivers and breast benign patients' primary caregivers were compared. The factors of the life satisfaction in primary caregivers of breast cancer patients were analyzed. Results The life satisfaction was poorer in the breast cancer patients' primary caregivers than in the breast benign patients' primary caregivers (P<0.01). The life satisfaction in the breast cancer patients' primary caregivers was correlated with the stage of breast cancer, course of disease, primary caregivers' age and family monthly income (P<0.05). Conclusion The life satisfaction in breast cancer patients' primary caregivers is worse and is related with stage of breast cancer, course of disease, primary caregivers' age and family monthly income.

Objective:To investigate the effect of Rab7 on cytokine induced by TLR7 (Toll like receptor-7) R848 activated in Raw264.7,and discusses the influence of Rab7 on MAPK signal transduction.Methods: TLR7 downstream cytokines such as TNF-α,IL-6,IFN-α,IFN-β and IP-10 activated by R848 were detected through Q-PCR in Rab7 silenced mouse macrophages,and then analysis of phosphorylation of MAPK determined with Western blot showed the effect of Rab7 on signal transduction of MAPK.Results: Rab7 inhibit production of cytokine activated by TLR7,and also,Rab7 had an inhibitory effect on MAPK signal pathway.Conclusion: The experimental results further illustrate that the Rab7 is the TLR7 signal transduction pathway negative regulatory factor,and to participate in MAPK signaling pathway.

Objective To summarize the experience of surgical treatment in patients with uremia and severe coronary artery disease, and reduce the perioperative risk thereof. Methods Sixteen chronic renal failure patients who were received haemodialysis and underwent coronary artery bypass grafting (CABG) during the period of February 2009 to December 2016 in Tianjin First Central Hospital were assessed in this retrospective study. Of the 16 patients, 8 patients and 6 patients were treated with off pump and on pump CABG respectively, one patient was treated with CABG and resection of ventricular aneurysm, and one patient was treated with CABG and tricuspid valve replacements. The renal function changes in preoperative and postoperative periods, 2-day and 1-week after surgery were observed. Echocardiography was used to evaluate cardiac function. The improvement of angina was recorded. Results Fourteen patients were successfully withdrawn from ventilator therapy within 24 h after surgery. The tracheal intubation was removed 65-hour after surgery in one patient. One patient died of multiple organ failure on the seventh day after surgery. The average length of ICU staying and in-hospital stay were (125.5 ± 21.6) h and (28.6 ± 7.4) days respectively. The serum creatinine (sCr) and blood urea nitrogen (BUN) were higher in two days after surgery than those before the operation (P < 0.05). Fifteen patients which followed up (the final follow-up date was February 2017) showing cardiac functionⅠ-Ⅱ, ejection fraction (EF)>0.40, and no angina occurred. Conclusion CABG is relatively safe for patients with end-stage renal disease and severe coronary artery disease. CABG can significantly eliminate angina symptoms with satisfactory clinical effect.

Objective To study the relationship and clinical significance of hepatitis B genotype distribution in Xi'an City and clinical relative indicators.Methods The nested PCR was used to amplify HBV DNA in 389 serum samples from HBV infected pa-tients in Xi'an City ,then polymerase chain reaction restriction fragment length polymorphism (PCR-RLFP) was used to identify HBV genotypes.Results Among 389 cases of HBV Infection in Xi'an City ,58 cases of HBV B genotype accounted for 14.9% (58/389) ,326 cases of HBV C genotype accounted for 83.8% (326/389) and 5 cases of HBV B/C mixed type accounted for 1.2% (5/389).The gender ,HBeAg positive rate ,HBV DNA load level ,ALT and AST had no statistical difference between HBV genotype B and C with the patients(P>0.05);There was no statistically significant in the distribution of B and C genotypes between the pa-tients with chronic hepatitis B and HBV carriers (P>0.05) ,but it had statistical difference between liver cirrhosis and hepatocellu-lar carcinoma(P<0.05).HBV genotype C was easier to develop liver cirrhosis even liver cancer than genotype B.Conclusion The three kinds of HBV genotype B ,C and B/C exist in the HBV infected persons in Xi'an City ,with the genotype C as the main geno-type ,genotype B takes the second and mixed genotype B/C is minimal.The liver cirrhosis occurrence has a certain relationship with the genotype C ,which suggesting that the genotype C is more likely to develop liver cirrhosis.

The incidence of dextrocardia is lower. The dextrocardia is often associated with congenital anatomical abnormalities. The patient with normal cardiac structure of dextrocardia and severe coronary heart disease that needs coronary artery bypasss is rarer. This article summarizes the perioperative management and surgical experience of dextrocardia with bypass surgery via a clinical case.

Objective To investigate the correlation between ankle-brachial index and ultrasonography in lower ex- tremities vascular in type 2 diabetic patients.Methods 218 type 2 diabetic patients were enrolled,and ankle-brachial index(ABI)measurements and uhrasonography in lower extremities vascular were performed in all patients.Lower extremi- ties vascular disease(LEVD)were divided into six species according to the uhrasonography results and scored in accord- ante with its serious degree,then investigate the correlation between ABI and uhrasonography results score.All patients were divided into deferent groups according to uhrasonography results and ABI range,and then compared their deference. Results The lower the ABI,the more serious of the LEVD showed by ultrasonography.ABI and ultrasonic inspection score was significantly negatively correlated(r=-0.65,P
